In this talk I give an overview of IBM's efforts to create a VM-agnostic toolkit of runtime components from the mature J9 Java Virtual Machine (JVM). I provide a summary of the motivations behind this project, talk about some important proof points with CPython and Ruby MRI, describe the motivations behind an open community for this technology, and discuss the many challenges with creating a runtime agnostic Just In Time compiler from the Testarossa Java JIT.
